Human is a kind of advanced intelligent animal that loves thinking, which is also the fundamental difference between human and animal. It is precisely because of this trait that human beings seem to be full of curiosity about everything in the world and challenging nature. So people seek the answer by trying to explore all the unknown things.

Mankind's quest for the "top of the world" - Mount Everest has never stopped moving forward. Even knowing that there are many difficulties waiting for them on Mount Everest, mankind has never given up its exploration. For a long time, human beings have explored Mount Everest for many times, and the regulatory exploration results are not satisfactory, but every exploration of human beings has new discoveries.
